We have the Loving Family one that someone on Freecycle gave us years ago. DD has had it since 18 mths. Nana bought a whole heap of furniture for it too for one of her birthdays. It was never an issue that it was the second stage one and we had no issues with the furniture being too small, etc.

DD still loves it and plays with it at four. I'm hoping to get her a really nice wooden one when she's a bit older. 'Cause she really needs more toys!
